You can download bitcoind and bitcoin-cli from lbtc.io. I found there is no directly URL to download, so I downloaded them manually and put it into my own github repository. You should ALWAYS download the software from lbtc.io.

4. Config Swap Space

Running a full bitcoin node uses a little over 1GB of memory, and I don’t know how much memory it needs to run a Lighting BTC node. The node I created has 16GB, but in case the one you run has less memory, I’ll make some spare “virtual memory” using swap space.
